I remember seeing a mention of a food-based evolution and I really support that idea. France has some of the finest food in the world at least in my opinion so it'd definitely be interesting to see something like Feebas to Milotic again except instead of poffins perhaps if you made a certain dish and fed it to your Pokemon a certain amount of times, the Pokemon would evolve? Just a thought :3.

Some of the dishes could even include frog legs, but then again I'm not sure if Game Freak would decide to put that in :B. But any fine-tasting or famously known French food :3.
